Menu
As of now I am using the JavaScript search method to replace some text in body HTML like below..
Suppose my html is
<body>
<div> I am in body...</div>
</body>
Then I am using the below approach
var body = $(body);
var text = body.html();
text = text.replace('I am in body...','Yes');
body.html(text);
But I could see slow page search in browsers like IE..
Please suggest me to improve this and also please let know if there are any plugins to search and match a string even if it contains any html tags in it.. Like below
<body>
<div><span>I </span> am in body...</div>
</body>
With the current method I cannot match this..
If i use
$('*:contains("some search text string")');
This will match the DIV and BODY as well.. But here I want to search the html text not parent element... Thanks

The <input type="search"> defines a text field for entering a search string. Note: Remember to set a name for the search field, otherwise nothing will be submitted. The most common name for search inputs is q.
The HTML <strong> element defines text with strong importance. The content inside is typically displayed in bold.
The <em> HTML element marks text that has stress emphasis. The <em> element can be nested, with each level of nesting indicating a greater degree of emphasis.
You should take a look at :
ranges:(to modify text without overwriting the complete body)
IE: http://msdn.microsoft.com/en-us/library/ms535872%28v=vs.85%29.aspx
Others: https://developer.mozilla.org/en/DOM/range
find()/findText()(to create the ranges)
IE: http://msdn.microsoft.com/en-us/library/ms536422%28v=vs.85%29.aspx
Others: https://developer.mozilla.org/en/DOM/window.find
(Opera doesn't support find or findText)
Regarding to that question a small modification:
<html>
<head>
<script>
function fx(a,b)
{
if(window.find)
{
while(window.find(a))
{
var rng=window.getSelection().getRangeAt(0);
rng.deleteContents();
rng.insertNode(document.createTextNode(b));
}
}
else if(document.body.createTextRange)
{
var rng=document.body.createTextRange();
while(rng.findText(a))
{
rng.pasteHTML(b);
}
}
}
</script>
</head>
<body onload="fx('I am in body...','Yes')">
<div>Oh <span>I </span>am in body...<i>, wonderful</i></div>
</body>
</html>
